Haohui Mai commented on HDFS-8493:
----------------------------------
{code}
+ res = FSDirTruncateOp.truncate(this, src, newLength, clientName,
+ clientMachine, mtime, toRemoveBlocks, pc);
+ stat = dir.getAuditFileInfo(dir.getINodesInPath4Write(src, false));
{code}
{{dir.getINodesInPath4Write()}} needs to be in the fsd lock. The easiest way to
change is to make {{FSDirTruncateOp.truncate()}} returns a object that contains
both the results and the audit file info. For example,
{code}
static class TruncateResult {
final boolean result;
final HdfsStatus stat;
...
}
{code}
> Consolidate truncate() related implementation in a single class
